I would love to find or make a wide bumper (like chubbysuncle I believe) to prevent any front end damage. My shocks keep getting mangled.
As far as the solidness of the arms, they arent that stiff and the plastic will still allow some give, but you really have no idea how much play thay had, at least the driver side. The guy at my LHS noticed it right away. BTW, aside from that, the dude was pretty impressed with the build of the VOLCANO, and he primarily deals with Traxxass...
